Title:
LIGHTING EQUIPMENT WITH WIND TURBINE GENERATOR
Document Type and Number:
Japanese Patent JP2019085937
Kind Code:
A
Abstract:
To provide lighting equipment with a wind turbine generator which can prevent resonance with a windmill as an excitation source by raising a resonance frequency of the lighting equipment as a whole by increasing the support rigidity of a foundation while suppressing an increase of a mass of the foundation.SOLUTION: In lighting equipment with a wind turbine generator, at least the wind turbine generator 2 and the lighting equipment 4 are arranged at a columnar support 1 which is built on the ground surface. Electricity generated by the wind turbine generator 2 is accumulated in an accumulator 5, and the lighting equipment 4 is lit by using the electricity which is accumulated in the accumulator. The lighting equipment has a foundation 10 to which a lower end of the columnar support 1 is fixed, and which supports the columnar support 1 to the ground 12. A maximum value of a dimension progressing toward a horizontal plane of a bottom surface of the foundation 10 is larger than a height dimension of the foundation 10.SELECTED DRAWING: Figure 2
